When you see the BB's 7510/7520 etc advertised on websites and elsewhere, it shows the screen in this pearly white color. My screen normal color is this "dark tan" dirty look. Is there a way to change the screen color to White?

One time I was invited backstage to check out a fashion show in New York during Fashion week. I quickly caught eye with a few models and struck a conversation with some of them while they await to be finshed up. I moved on and my buddy approached me to ask how my conversation went with the supermodel. Perplexed, I asked what supermodel are you referring to? To make a long story short, the image of the models that many, including myself, would drool over in editorial work was quite shocking to me when you meet some of these girls up close. It's all artistic touching up that make some of these models seem a complete different image that you have in your mind. Although the BB 7520 is quite white the 7510 is not as white but Nextel advertising made it seem that way to appear more attractive.
